• What is the cause and solution for SAP error message ECATT_TDW058 - Unstructured TDC parameter &1 doesn't fit to structured TC parameter &2 ?

  The SAP error message ECATT_TDW058 indicates a mismatch between an unstructured Test Data Container (TDC) parameter and a structured Test Case (TC) parameter in the context of eCATT (extended Computer Aided Test Tool). This error typically arises when the data types or structures of the parameters do not align as expected.
  Cause:
  
  
  Parameter Mismatch: The unstructured TDC parameter is not compatible with the structured TC parameter. This can happen if:
  
  The unstructured parameter is expected to be a simple data type (like a string or number), but the TC parameter is defined as a complex structure (like a table or a record).
  The data types do not match (e.g., trying to assign a string to an integer field).
  The number of elements in the unstructured parameter does not match the expected number of elements in the structured parameter.
  
  
  
  Incorrect Mapping: The mapping between the TDC and TC parameters may not have been set up correctly, leading to this error.
  
  
  Solution:
  
  
  Check Parameter Definitions: Review the definitions of both the unstructured TDC parameter and the structured TC parameter. Ensure that:
  
  The data types are compatible.
  The number of elements matches if applicable.
  
  
  
  Adjust Parameter Types: If necessary, modify the unstructured parameter to match the expected structure of the TC parameter. This may involve:
  
  Changing the data type of the unstructured parameter.
  Restructuring the data to fit the expected format.
  
  
  
  Review Mapping: Ensure that the mapping between the TDC and TC parameters is correctly defined. If you are using a mapping function, verify that it is correctly implemented.
  
  
  Testing: After making adjustments, run the test case again to see if the error persists.
  
  
  Related Information:
  
  eCATT Documentation: Refer to the official SAP documentation for eCATT for detailed information on parameter types and how to define them correctly.
  SAP Community: Check forums and community discussions for similar issues and solutions shared by other users.
  Debugging: If the issue is complex, consider using debugging tools within SAP to trace the execution and identify where the mismatch occurs.
  
  By following these steps, you should be able to resolve the ECATT_TDW058 error and ensure that your test cases run smoothly.
